Two members have given you valid resources for you to use to figure out how to read a configuration file.

Demanding code from people who are generously giving their time to assist you will only result in your query and your member account being marked as abusive.

Read the articles carefully, try using some of the examples shown in the articles. Then show what you have tried and we can help you.

Solution 1

You'll need to add a reference to System.Configuration in your references folder.
Then use the <code>ConfigurationManager class.

Also refer to How to get Connection String from App.Config in C#[^] as an additional reference.

Solution 3

Try this

C#

XElement root = XElement.Load("your app config path"); //
          var topnode = root.Elements("LibrarySetting").Descendants<XElement>("Country").ToList();
          var DailyPenaltyFees = topnode.Attributes("DailyPenaltyFee").Select(k => k.Value).ToList();
